D&D 5E 5e Updates: Monstrous Compendium


What pantheons do you have planned?
I would love to cover all the ones in the 1e Deities and Demigods, plus:
  • Oerth Mythos
    • TBD
  • Abeir-Toril Mythos
  • Theros Mythos
    • Heliod (Mythic, CR 30) by Ash Mantle

Earth was kind of the original D&D setting before Gygax made up a different universe.
"Mordenkainen was an acquaintance of Elminster's; the two had met on numerous occasions at Ed Greenwood's house on Earth to exchange spells and lore."
I am still not sure what your point is? Are you going somewhere with this line of comments? Do you wish to influence what epic monsters or deities I portray? I'm just not sure what your trying to accomplish.

Neither am I. But I prefer not including most of the human gods, except the Greek ones as those for the fantasy feel. But IMO it's awkward including things that are actually worshipped today, like the animals and Ra and Osiris, that just weirds me out. But do what you prefer.
Ok, I get that. It makes some uncomfortable, but not sure why you would single out Greek as there are people today who worship Greco-Roman deities. Also, Oerth doesn't use real world mythologies and that is what you quoted. Though you said Earth, you quoted the "Oerth Mythos" so that is why I was confused.

Of the RL religions I will definitely do the Greco-Roman & Norse Mythos as I know those fairly well. After that I may do the Abrahamic Mythos as the next one I know the most about. If I truly want to do the rest of the 1e Deities and Demigods I may need some help or do some more research.


Deities & Demigods included Japanese, Chinese, Sumerian, and other pantheons. As far as I am aware Oerth is synonymous with Earth. Is Deities and Demigods the same way?
Ok, you are wildly mistaken. Oerth is the world of Greyhawk and includes (among many more, also note these were all originally Oerth gods before some migrated to other settings):
Wee Jas
St. Cuthbert
Corellon Larethian

In Deities and Demigods, the only gods from Oerth listed are the Nonhumans' Deities.

The were not specifically called our as coming from Oerth (not even sure it was true setting at that time), but they all came from Greyhawk / Oerth.


OK, I have posted the first draft of my introduction to the Greco-Roman Mythos. This a reimaging of Greco-Roman mythology in the context of the D&D Multiverse. This will become more apparent with each deity entry as well.

This a draft and I eventually want to get a little more about the Olympic Pantheon in here, but is a start and origin story or sorts. Let me know what you think.

I will be posting a few Olympians and then I will get back to the dragons.


Is the white dragon's breath not supposed to do half damage on a passed save?

I may be trying out one in my game tomorrow (slightly adjusted, it will be a ghost!), so I want to make sure the stats are right.

No, that was an accidental casualty of the rewrites and adding the frozen condition. I've added it back now.



Beyond to the lair of Dragotha, the undead dragon where fabulous riches and hideous death await. - map of White Plume Mountain


Dracolich by Kanizo

Little remains of Dragotha’s flesh to indicate that this undead horror was once a red dragon. Twin horns snake from the back of his skull; smaller ones are blackened by flame, cracked, splintered, or missing altogether, leaving dark holes that now hold only burrowing parasites. Tattered mem-branes clothe his wings while mummified tissue clings to his tail and massive rib cage. Webs hang from his frame while bright green maggots squirm in his joints. If the presence of this massive skeletal dragon were not enough, Dragotha’s baleful blue stare radiates all the malice and evil that fuels this undead monstrosity. To behold him is to see death.

Consort of Tiamat. Ages ago, Dragotha was a celebrated consort of Tiamat, a mighty red dragon chosen for his strength and cunning, as well as unswerving loyalty to his mistress. He was dutiful and felt an earnest affection for the goddess, sparing him her wrath far longer than any other consort. For all the Dark Lady doted on Dragotha, though, he had little protection from ambitious dragons that craved his vaunted position. Through his long years, he squared off against numerous dragon ascendants, each more powerful than the last.

Dragotha’s fall came when a vicious dragon challenged him. He dealt with the upstart as he had others, tearing out its throat and devouring its heart. Unknown to him, his rival was the son of Tiamat, whose death enraged his mistress. Realizing his doom was at hand, Dragotha fled Tiamat’s realm to find refuge in the mortal world. Even far from cruel talons of his former lover, he knew her servants would find him—and when they did, they would kill him.

The Dragon of Death. Dragotha sought out a powerful priest of the death god, a vile human named Kyuss, who promised immortality in exchange for the dragon’s service. Dragotha agreed, and not long afterward, Tiamat’s spawn indeed descended on the dragon and killed him. As Dragotha lay, broken and dying, Kyuss made good on his vow. Instead of restoring him to life, however, Kyuss transformed Dragotha into a terrifying dracolich.

After this final betrayal, Dragotha withdrew to a hidden cave, contaminating the lands around. Hoarding treasures in the endless depths, the great monster rarely stirs these days. Rumor holds that the dracolich was drawn out of its lair once when adventurers breached the dungeons of White Plume Mountain, and again when Kyuss's cultist sought to elevate the undead priest to godhood.

As powerful as Dragotha is, its most hated enemies are even more so. If there are two beings in the Multiverse whom Dragotha can be said to despise above all others, they would by Tiamat, the Queen of Dragons, and Kyuss, the Worm that Walks. The former is a goddess; the latter and undead demigod. Both granted Dragotha great power, great authority - and both ultimately betrayed him, leading to his curren adhorrent state.

Many of Dragotha's current schemes are devoted to wreaking horrible vengeance upon those who turned on him - and yet the undead dragon is nothing if not cunning and oh, so patient. At times the dracolich has masqueraded as a loyal servant to both entities, most recently taking part in teh convoluted schemed intended to grant Kyuss true godhood. Though it led the Worm that Walks to believe that its service was genuine, Dragotha sought only to grow close enough to Kyuss to slay the vile priest. It hopes for the opportunity to commit deicide against Tiamat as well, though it is unsure how. Some sages speculate that it seeks to usurp her place as the god of dragons, but Dragotha - though ambitious - currently shows no signs of any such objective. Lately, Dragotha has contemplated turning the followrs of Kyuss and Tiamat against each other, but as yet hasn't come up with a viable way of going about it.

Because of this burning hatred it holds for two beings of ultimate evil, Dragotha could potentially wind up allied with good-aligned adventurers, if their objectives overlap with its own. Anyone who proves worthy, and demonstrates the willingness to take on either the worshipers of Tiamat or mad cults of Kyuss, attracts Dragotha's interest.

Minions of Death. Such is Dragotha’s reputation that the dracolich has acquired misguided cultists who erect shrines in the wreckage of its domain. Since the undead dragon rarely has use for living servants, these feckless acolytes often receive the curse of undeath as their reward for constant service. Thus, over the centuries Dragotha has cultivated a vast army of undead to serve its needs.

Each creature in the area must make DC 25 Dexterity saving throw, taking 33 (6d10) necrotic damage on a failed save, or half as much damage on a successful one.

Withering Grasp. The dragon selects up to four targets it can see within 120 feet of it, which are grasped by a giant spectral skeletal hand. Each target must make a DC 26 Constitution saving throw or be restrained and loose any resistance to necrotic damage for 1 hour. A restrained target can make an additional saving throw at the end of each of its turns, end the effect on itself on a success.

Frightful Presence. Each creature of the Dragotha’s choice within 240 feet of the Dragotha and aware of it must succeed on a DC 26 Wisdom saving throw or become frightened for 1 minute and suffer an indefinite madness (DMG pg 260). A creature can repeat the saving throw at the end of each of its turns, and it is no longer frightened on a success. If a creature’s saving throw is successful or the effect ends for it, the creature is immune to Dragotha’s Frightful Presence for the next 24 hours.

Breath Weapons (1/Rest). Dragotha uses one of the following breath weapons. Additionally, targets that fail their saving throw by 10 or more (DC 15) take maximum damage from these attacks. Additionally, any creature that takes damage from the Dragotha's breath weapon must make an additional DC 25 Constitution saving throw or its hit point maximum is reduced by an amount equal to half the necrotic damage taken. The reduction lasts until the target finishes a long rest. The target dies if this effect reduces its hit point maximum to 0.

A creature reduced to 0 hit points by this attack dies and is burned to a pile of ash.

Necrotic Breath. Dragotha exhales necrotic energy in a 200-foot cone or eight 25-foot-by-25-foot contiguous areas within 100 feet of it. Each creature in that area must make a DC 25 Dexterity saving throw, taking 159 (29d10) necrotic damage and be incapacitated until the end of its next turn on a failed save, or half as much damage on a successful one. Additionally, any magic or active spell of 9th level or lower in the area ends.

Recharge. Dragotha recharges its breath weapon and it can use it on its next turn.

Dragotha can take 3 legendary actions, choosing from the options below. Only one legendary action option can be used at a time and only at the end of another creature’s turn.

Any creature that starts or ends its turn in the area of the aura, or that touches or hits Dragotha with a melee attack while in the aura takes 21 (6d6) necrotic damage. In addition, Dragotha sheds dim green light in a 60-foot radius and it gains a +4 bonus to its AC from ranged attacks that originate outside the aura while the aura is active.
Paralyzing Gaze (Costs 2 Actions). Dragotha choses a point it can see within 150 feet of it and forces any creature within a 20-foot radius of that point to look into its eyes. The target must make a DC 26 Constitution saving throw or be paralyzed for 1 minute. The target can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.
Draconic Fury (Cost 3 Actions). Dragotha makes a bite and two claw attacks
Spellcasting (Costs 3 Actions). Dragotha cast a spell.


Dragotha as a Mythic Encounter
Dragotha is a mythic encounter and gains the mythic trait when its hit points are reduced to 0 for the first time in an encounter. When this happens, Dragotha unleashes its full might and it can choose one of its mythic actions when it uses a legendary action.

Read or paraphrase the following text when Dragotha uses its Great Wyrm trait:

Future descriptive text goes here

Fighting Dragotha as a mythic encounter is equivalent to taking on two CR 29 creatures in one encounter. Award a party 270,000 XP for defeating Dragotha after it uses Great Wyrm.


In the shadow of fabled White Plume Mountain lies a dismal land, a blighted place of gnarled trees, bone fields, and roaming, hungry undead. This the lair of Undead Dragon: Dragotha. More to come...

If Dragotha is encountered in its lair, it has a challenge rating of 30 (155,000 XP / 310,00 XP).

Lair Actions
On initiative count 20 (losing initiative ties), Dragotha takes a lair action to cause one of the following effects; the dragon can't use the same effect two rounds in a row:

  • Dragotha rolls a d8 and regains a spell slot of that level or lower. If it has no spent spell slots of that level or lower, nothing happens.
  • Grasping skeletal hands erupt in a 20-foot radius centered on a point on the ground that Dragotha can see within 240 feet of it. That area becomes difficult terrain, and each creature there must succeed on a DC 20 Strength saving throw or be restrained by the hands. A creature can be freed if it or another creature takes an action to make a DC 20 Strength check and succeeds. The skeletal hands turn to dust when Dragotha uses this lair action again or when it is reduced to 0 hit points.
  • Dragotha targets any number of creatures it can see within 60 feet of it. No target can regain hit points until initiative count 20 on the next round.

Simple, and yet can be really scary with its solid Life Drain effect. You might consider buffing this up to a CR 9, as that is when party's are more expected to have Greater Restoration type effects handy, otherwise this creature might really wreck a player's entire adventuring day.

The exhaustion goes away on a long rest, so I don't think it is to terrible.

Its fair, and probably on the DM to consider. If the DM wants to put it in at the beginning of the day, it will have a much bigger impact compared to at the end.....but lots of monsters have that kind of consideration.

As soon as I saw it, my first thought was have it pop through the wall of a dungeon after the party just took out a boatload of kobolds or something, and watch the undead rise :)
